Great plan. I have a little more time now, so I broke it down by class.
Barbarian: Grimm done
Options: Kage, Atomos, Little John, Gormek
I think it’s Kage hands down. One of the best heroes, wide range on offense, defense, and titans.
Cleric: Rigard done
Options: Agwe, Boril
I don’t love either and would consider waiting. If you want to proceed, I vastly favor Boril > Agwe for for various raid tournament configurations.
Druid: Caedmon done
Options: Gadeirus, Melendor
Both are very reasonable. Caedmon being an option for when you need a green dispel lessens Mel’s claim here. I’d go whichever you feel will be used more often when you need a green healer.
Fighter: Colen done
Options: Magni, Boldtusk, and maybe Hu Tao (you wrote Hu Kong, so I’m not sure - doesn’t matter though since the answer is NOT Hu Tao)
Magni is a very reasonable answer here, though I love BT. His special and talent are very well matched. If you are happy with Colen, great. But if not, I’d consider re-setting Colen, shifting those to BT, then doing Magni.
Monk: Wu Kong done
Options: Li Xiu
I’d wait, unless you feel strongly that all emblems need to be used and there is very little chance to get an upgrade here in the medium term future. Or go ahead with LX if you’re comfortable using a reset later.
Paladin: Richard at +7
Options: Justice, Cyprian, Sonya
I think what you’re doing is fine, unless you’re looking to shift your defense (like if you need a yellow tank, in which case I think Justice is a reasonable answer).
Ranger: Buddy done
Options: Chao, Tiburtus, Triton
Tiburtus and Triton are both reasonable. Looking at the rest of your roster I favor Tiburtus. For blue 3tacks you have Kiril, Grimm, Richard, and Magni - that’s plenty and I can’t think of spots where I’d bring even emblemed Triton over them. For purple 3tacks you have Kage, Proteus, Sartana, and Sabina / Rigard. Tiburtus rounds out that group very well so you have a full slate of options depending on what skill you need in that stack.
Rogue: Scarlett done
Options: Marjana, Danzaburo, Kelile
I’d just go ahead with Marjana here. She’s the strongest option and could be an option in a variety of offensive and defensive teams by dint of being a fast sniper.
Sorcerer: Sabina done
Wizard: Proteus done
Options: Onatel, Kiril, Sartana
Some strong options here. I’d probably favor whoever you use the most. I note that holy seems to be your weakest element, so would take a very long look at Onatel. I use her extensively so I’ll also add that I think she’s incredibly successful as part of the minor stack in a 3/2, and even rolling solo in a 3/1/1. Her skill can dominate and take over an entire raid, all by herself, she’s durable, and her element link healing skill is actually pretty significant in terms of keeping her alive as a fight goes on.
